Datum Precedence and Degrees of Freedom
By Janet Braun
Datum precedence is a fundamental principle in the design and manufacture of mechanical parts and assemblies.
It refers to the order of importance assigned to different datums, which are specific points, lines, or planes on a part, which are used as references for measurement and geometric tolerances.

SIPOC
In this module, we'll be introducing you to SIPOC, a powerful tool that can help you improve your business processes. It's a high-level process mapping tool that helps you identify the key components of a process and how they relate to each other. SIPOC diagrams are often used in Six Sigma and Lean methodologies, but they can be useful for any process improvement initiative. We’ll explain the key SIPOC components and demonstrate how to build one. Then, we’ll walk through a few scenarios and let you build your own.
